The immature stages of Rachiplusia nu (Guenée) are redescribed and illustrated, according to current standards of descriptive patterns. The immature stages of R. nu were obtained from laboratory cultures under controlled conditions of temperature at 27 ± 2ºC, 14:10 (light/darkness) artificial photoperiod and 70-75% of relative humidity. For the first time, the larval instars previous to the larvae mature are described. All immature stages were compared with those of Pseudoplusia includens (Walker), with which they can often be confused in the field. The estimation of the larval age allowed to determine that the highest rate of growth takes place in the fourth larval instar and then decreases gradually to mature larva. KEYWORDS. Egg. Larva. Pupa. Morphology. Rachiplusia nu. RESUMEN. Se redescriben e ilustran todos los estados preimaginales de Rachiplusia nu (Guenée) de acuerdo a estándares actualizados de patrones descriptivos. Los estados inmaduros de R. nu fueron obtenidos a partir de crías de laboratorio, bajo condiciones controladas de 27 ± 2ºC de temperatura, 14:10 (luz/oscuridad) de fotoperíodo artificial y 70-75% de humedad relativa. Por primera vez, se describen todos los estadios larvales previos al de larva madura. Todos los estados inmaduros fueron comparados con aquellos de Pseudoplusia includens (Walker), con los que usualmente pueden ser confundidos a campo. La estimación de la edad larval permitió determinar que la mayor razón de crecimiento se verifica en el cuarto estadio larval y de allí decrece paulatinamente hacia larva madura. PALABRAS CLAVE.

  • 197 Section 9 Sunflower (Helianthus
    SECTION 9 SUNFLOWER (HELIANTHUS ANNUUS L.) 1. Taxonomy of the Genus Helianthus, Natural Habitat and Origins of the Cultivated Sunflower A. Taxonomy of the genus Helianthus The sunflower belongs to the genus Helianthus in the Composite family (Asterales order), which includes species with very diverse morphologies (herbs, shrubs, lianas, etc.). The genus Helianthus belongs to the Heliantheae tribe. This includes approximately 50 species originating in North and Central America. The basis for the botanical classification of the genus Helianthus was proposed by Heiser et al. (1969) and refined subsequently using new phenological, cladistic and biosystematic methods, (Robinson, 1979; Anashchenko, 1974, 1979; Schilling and Heiser, 1981) or molecular markers (Sossey-Alaoui et al., 1998). This approach splits Helianthus into four sections: Helianthus, Agrestes, Ciliares and Atrorubens. This classification is set out in Table 1.18. Section Helianthus This section comprises 12 species, including H. annuus, the cultivated sunflower. These species, which are diploid (2n = 34), are interfertile and annual in almost all cases. For the majority, the natural distribution is central and western North America. They are generally well adapted to dry or even arid areas and sandy soils. The widespread H. annuus L. species includes (Heiser et al., 1969) plants cultivated for seed or fodder referred to as H. annuus var. macrocarpus (D.C), or cultivated for ornament (H. annuus subsp. annuus), and uncultivated wild and weedy plants (H. annuus subsp. lenticularis, H. annuus subsp. Texanus, etc.). Leaves of these species are usually alternate, ovoid and with a long petiole. Flower heads, or capitula, consist of tubular and ligulate florets, which may be deep purple, red or yellow.

    Contributions Toward a Lepidoptera (Psychidae, Yponomeutidae, Sesiidae, Cossidae, Zygaenoidea, Thyrididae, Drepanoidea, Geometroidea, Mimalonoidea, Bombycoidea, Sphingoidea, & Noctuoidea) Biodiversity Inventory of the University of Florida Natural Area Teaching Lab Hugo L. Kons Jr. Last Update: June 2001 Abstract A systematic check list of 489 species of Lepidoptera collected in the University of Florida Natural Area Teaching Lab is presented, including 464 species in the superfamilies Drepanoidea, Geometroidea, Mimalonoidea, Bombycoidea, Sphingoidea, and Noctuoidea. Taxa recorded in Psychidae, Yponomeutidae, Sesiidae, Cossidae, Zygaenoidea, and Thyrididae are also included. Moth taxa were collected at ultraviolet lights, bait, introduced Bahiagrass (Paspalum notatum), and by netting specimens. A list of taxa recorded feeding on P. notatum is presented. Introduction The University of Florida Natural Area Teaching Laboratory (NATL) contains 40 acres of natural habitats maintained for scientific research, conservation, and teaching purposes. Habitat types present include hammock, upland pine, disturbed open field, cat tail marsh, and shallow pond. An active management plan has been developed for this area, including prescribed burning to restore the upland pine community and establishment of plots to study succession (http://csssrvr.entnem.ufl.edu/~walker/natl.htm). The site is a popular collecting locality for student and scientific collections. The author has done extensive collecting and field work at NATL, and two previous reports have resulted from this work, including: a biodiversity inventory of the butterflies (Lepidoptera: Hesperioidea & Papilionoidea) of NATL (Kons 1999), and an ecological study of Hermeuptychia hermes (F.) and Megisto cymela (Cram.) in NATL habitats (Kons 1998). Other workers have posted NATL check lists for Ichneumonidae, Sphecidae, Tettigoniidae, and Gryllidae (http://csssrvr.entnem.ufl.edu/~walker/insect.htm).

Aiming to understand how Accepted 17 January 2021 the assemblages of Plusiinae are structured by agricultural occupation and climate, this study used automated Available online 24 February 2021 light traps sampled moths in 18 sites in Brazil, across a broad latitudinal gradient. Our data has demonstrated Associate Editor: Thamara Zacca that climate variables prevails as the most important variables influencing both the composition of Plusiinae and the abundance of its dominant species Chrysodeixis includens. On the other hand, the lack of significance found for the effect of variables representing agricultural occupation evidences that pest species are present Keywords: both in agricultural and natural ecosystems, also sharing similar abundances at those locations. In other words, Abundance instead of following a gradient of agricultural occupation (e.g. crop sizes around sample sites) the composition Assemblage structure of these extremely polyphagous insects is more clearly shaped by the latitudinal gradient, in which temperature Looper moths and precipitation are better predictors. Thus, in contrary to our expectations, pest species inhabits both natural Pest species and agricultural landscapes at similar latitudinal sites, probably due to their wide polyphagy spectrum.

Holley Center for Agriculture and Health 538 Tower Road Ithaca, New York 14853-2901 (USA) ii New nomenclatural rules bring new challenges, and new taxonomic revisions for entomopathogenic fungi Richard A. Humber Insect Mycologist and Curator, ARSEF February 2014 The previous (2007) version of this introductory material for ARSEF catalogs sought to explain some of the phylogenetical rationale for major changes to the taxonomy of many key fungal entomopathogens, especially those involving some key conidial and sexual genera of the ascomycete order Hypocreales. Phylogenetic revisions of the taxonomies of entomopathogenic fungi continued to appear, and the results of these revisions are reflected in the ARSEF catalog as quickly and completely as we can do so. As many of people dealing with entomopathogenic fungi are already aware, there has been one still recent event that has a more far-reaching and pervasive influence whose magnitude still remains to be fully appreciated, but that leaves much of the mycological world (including insect mycology) semiparalyzed by uncertainty and worried about the extent and impacts of changes that still remain unformalized and, hence, a continuing subject for speculation and prediction.

(Solanaceae)]. The specimens were collected in a Virginia tobacco field, in Venâncio Aires, State of Rio Grande do Sul. Caterpillars occurred in large infestations, causing important damage to tobacco leaves, and demanding chemical control to minimize losses. This occurrence indicates that this species can feed on Virginia tobacco, which corresponds to 80% of the tobacco area of Rio Grande do Sul, and so presents high risk to become an important pest in tobacco fields.
